This happened to me recently, there’s a group of people confusing me for a humanitarian artist because I stood up for her in front of the wrong people, and now I notice my copyrights/trademarks are intertwined with hers because the misconception is socially innate.
Absolutely nothing happened. She just said “sorry I mistook you for someone else” and I never saw her again.
Though I do remember I once mistook a random guy for one of my friends and showed him a meme. Then I realized he wasn’t my friend and he said “Sorry I’m not that guy, good meme though”
Same here: absolutely nothing happened.
